X1 = Signal Range Min (Electrical Input from Sensor)
X2 = Signal Range Max (Electrical input from Sensor)
Y1 = Gas Range Min
Y2 = Gas Range Max
Gas concentration (y) is calculated as follows:
y = (((Y2-Y1)/(X2-X1))*(x-X1))+Y1
Comment
If "Peak Hold" is enabled, and the gas reading rises above
the configured full scale value, the channel will display the
maximum gas reading that has been measured until it is reset
